Fig. 5 is the cross section of the wind path structure according to a kind of automatic cleaning equipment shown in an exemplary embodiment Sectional view;Wherein, when the automatic cleaning equipment shown in Fig. 5 be robot 100 as Figure 1-4 or During other similar devices of person, the wind path structure of this automatic cleaning equipment can correspond to above-mentioned robot 100 Cleaning systems 150.For the ease of describing, Fig. 5 shows that automatic cleaning equipment is in an exemplary enforcement Directional information in example, including the direct of travel along y-axis (in which it is assumed that y-axis left direction is forward direction Driving direction, i.e. "+";Y-axis right direction is backward driving direction, i.e. "-") and along z-axis Vertical direction.
As it is shown in figure 5, the wind path structure of automatic cleaning equipment may include that cleaning member 1, clean right As storage member 2, power part 3, one-level air channel 4 and light breeze road 5.Wherein, cleaning member 1, Cleaning object storage member 2 and power part 3 along automatic cleaning equipment direct of travel i.e. y direction successively Arrangement, and one-level air channel 4 is between cleaning member 1 and cleaning object storage member 2, light breeze road 5 between cleaning object storage member 2 and power part 3.So, the embodiment shown in Fig. 5 can To form following air channel: 4 → cleaning object storage member 2 → light breeze road, cleaning member 1 → one-level air channel 5 → power part 3 so that the wind that power part 3 produces can be realized by cleaning member by above-mentioned air channel 1 to the flowing of power part 3, and flow direction is illustrated by the direction of arrow in Fig. 5;Wherein, power The wind that parts 3 produce flows between cleaning member 1, one-level air channel 4 and cleaning object storage member 2 Time, can be delivered to clean object by cleaning objects such as dust that cleaning member 1 cleans, graininess rubbish In storage member 2, it is achieved clean operation.
Sweeping efficiency DPU is the accurate embodiment of the cleaning capacity of automatic cleaning equipment, by suction efficiency and rolling Brush sweeps both efficiency and together decides on, and suction efficiency discussed herein is main, and suction efficiency is dust removal ability Accurately embody, embody the efficiency converting electrical energy into mechanical energy, suction efficiency=suction power/input work Rate, input power is the electric energy of the input of blower motor, sucks power=air quantity * vacuum, input power After increasing to certain value, starting to produce the air quantity sucked, along with the increase of input power, air quantity constantly increases Adding, vacuum is gradually reduced, and sucking power is then first to increase to reduce afterwards, makes input power be operated in suction Enter in the scope that power is higher.
For same input power, air quantity and vacuum are all the biggest more can obtain high suction efficiency. The loss of vacuum reduces and depends on avoiding of leaking out, namely encapsulation process.The loss of air quantity reduces Depend on the smooth wind path structure without abrupt change, specifically include that from round brush lower end whether wind specifically Nondestructively entering air channel, wind blows to dirt box and enters during blower fan by wide-angle reflection from round brush lower end Number of times, duct cross-section amasss whether produce substantial amounts of turbulent flow etc. when changing.The overall structure of wind path sets Being counted as organic whole, the structural change of parts all can produce great variety to complete machine dust collection efficiency.
Because round brush is as cleaning member 1, its width the widest then single cleaning width is the widest, and dirt box is made For cleaning object storage member 2, parts are co-located in shell with road wheel etc. for it, and restricted width is not Can be the widest, and in order to increase vacuum fine pressure to be drawn into by rubbish in the middle of dirt box, the entrance of dirt box is the most not Can be the widest, between round brush and dirt box, therefore there is the first air channel, and cross section is the least;Going out of dirt box Mouthful by strainer filtering air, in order to avoid the blocking of filter screen, affect air channel unimpeded, and dirt box discharge area is logical The biggest, and blower fan is as power part 3, its entrance hole diameter then exports much smaller than dirt box, therefore dirt box And there is the second air channel between blower fan, and cross section is also the least.Although there is part automated cleaning at present Using such two air channels in the wind path of equipment, the Roomba series of such as iROBOT is swept the floor machine People, but and be provided without doing the wind path structure optimizing design for the two air channel.
Although it practice, wind path all can include round brush, dirt box, blower fan, two cross sections even can be there are The least air channel, but the difference of air channel shape makes suction efficiency far from each other.
Wind path in the disclosure makes the entrance air channel, round brush lower end of wind self-relocation, because floating round brush can be not Tightly can fit with ground in level region to be cleaned, wind loss is the least.Floating round brush Realize coming from the flexible material character in one-level air channel and the structure making round brush flexible up and down with topography variation sets Meter.
Round brush accommodates chamber through round brush and enters one-level air channel, and the shape in one-level air channel makes the fine pressure value of wind smooth Raise, rubbish is moved into obliquely dirt box;After the gradient in one-level air channel makes wind enter dirt box, Dirt box is left with big angle of reflection in dirt box top;The rubbish entering dirt box falls under gravity into dirt Cassette bottom portion, and the wind moved obliquely is blown out to export from filter screen after big angle of reflection by dirt box top, Enter light breeze road;Wherein, the purpose of design in light breeze road is to make the wind from filter screen blowout the fewest Loss ground enters blower fan mouth with certain orientation.
Below each structure in wind path is described in detail:
1, the structure in one-level air channel 4
In the technical scheme of the disclosure, by the guiding function in one-level air channel 4 so that power part 3 The dust etc. that cleaning member 1 cleans can be cleaned object and be delivered to clean object storage member by the wind produced In 2.

In this embodiment, by the bell mouth shape being configured to gradually successively decrease by the sectional area in one-level air channel 4, The static pressure making corresponding position is incremented by therewith, i.e. forms increasing suction;So, when dust, The cleaning cleaned parts of object 1 such as rubbish sweep and band is to behind one-level air channel 4, along with cleaning object progressively Away from cleaning member 1, progressively near cleaning object storage member 2 (the most progressively near power part 3), Although the sweeping power that cleaning member 1 applies to cleaning object is gradually reduced, but owing to power part 3 is to clearly The suction that clean object applies is gradually increased such that it is able to guarantee to clean object be attracted and be delivered to clean right As in storage member 2.
Further, when cleaning member 1 is round brush assembly, as it is shown in figure 5, the entering of one-level air channel 4 Mouthful end is towards the round brush 11 of round brush assembly, and arrival end 41 is vertical with direct of travel in the horizontal plane Width on direction (i.e. x-axis direction) is incremented by from the top down.In order to make it easy to understand, for shown in Fig. 5 One-level air channel 4 and round brush 11 between matching relationship, Fig. 6 shows one-level air channel 4 and round brush 11 The perspective view cooperated.As shown in Figure 6, near the entrance of round brush 11 on one-level air channel 4 End 41 has larger sectional area, the port of export 42 away from round brush 11 has small cross sections and amasss.Wherein, base In above-mentioned " being incremented by " feature of arrival end 41, the cross section of this arrival end 41 can be trapezoidal, and narrower The second edge 412 be trapezoidal upper base, the first wider edge 411 be trapezoidal bottom;When So, as long as meeting above-mentioned " being incremented by " feature, the cross section of arrival end 41 can also use other shapes, than As used arc etc. corresponding to two waists of above-mentioned " trapezoidal ", this is not limited by the disclosure.
In this embodiment, by using trapezoidal or similar meeting at the arrival end 41 in one-level air channel 4 The shape of above-mentioned " being incremented by " feature so that the static pressure of corresponding position is incremented by therewith, then when dust, Rubbish etc. cleaning object swept by round brush 11 and band to arrival end 41 time, power part 3 produce wind energy Enough provide enough suction so that the cleaning object being swept to arrival end 41 can be inhaled into clearly as much as possible In clean object storage member 2, contribute to promoting cleaning efficiency.
As it is shown in figure 5, the arrival end 41 in one-level air channel 4 can be connected to the round brush as cleaning member 1 The round brush storehouse 12 of assembly, and by the opening on this round brush storehouse 12 towards round brush 11;Wherein, such as Fig. 7 Shown in, one-level air channel 4 includes two sidewalls on the rotating direction of round brush 11: after being positioned at direct of travel The first side wall 43 of side, being positioned at the second sidewall 44 of the front side of direct of travel, both can pass through following side Formula configures.
1) the first side wall 43
In one embodiment, the first side wall 43 can be along the tangent line side of the circular cross-sectional area in round brush storehouse 12 To setting.Than as it is shown in fig. 7, round brush storehouse 12 can include left side arcuate structure and right side L on cross section The some such as type structure, wherein the arch section in the arcuate structure of left side is corresponding to the circle shown in Fig. 7 Dashed region, thus this circular dashed line region corresponding to this arch section can be equivalent to above-mentioned circle and cut Region, face;Correspondingly, the first side wall 43 in one-level air channel 4 can be along the tangent line side in this circular dashed line region To setting, such as in the relative position relation shown in Fig. 7, owing to one-level air channel 4 is positioned at round brush assembly Oblique upper and on direct of travel, be partial to the rear of round brush 11, thus the first side wall 43 can be along vertically Direction is arranged.
In this embodiment, after round brush 11 sweeps cleaning object from ground, cleaning object is first along round brush Gap motion between 11 and round brush storehouse 12;And along with cleaning object by roller brushes structure to one-level air channel 4 Movement, by the first side wall 43 is arranged along above-mentioned tangential direction so that cleaning object movement locus Flowing with wind direction all will not be by the stop of the first side wall 43, it is ensured that cleaning object passes through force one wind Road 4 enters in cleaning object storage member 2.
2) the second sidewall 44
In one embodiment, in conjunction with Fig. 5 and Fig. 7, when cleaning member 1 is round brush assembly, and force one wind When the rear of round brush 1 is partial in road 4 on direct of travel, the arrival end 41 in one-level air channel 4 is towards traveling Round brush 11 at front side (left side in the such as Fig. 5) obliquely downward in direction, the port of export 42 are connected to row Enter the inlet air cleaning object storage member 2 at rear side (right side in the such as Fig. 5) oblique upper in direction Mouthfuls 21, and the air outlet 22 of cleaning object storage member 2 is positioned at non-top sides (i.e. air outlet 22 not position At top side 23, such as Fig. 5 is positioned at right side wall).
Wherein, second sidewall 44 in one-level air channel 4 towards the oblique rear-inclined of horizontal plane (i.e. as close possible to water Plane), even if also the second sidewall 44 forms the angle the biggest with z-axis vertical direction.It practice, Owing to the inner space of automatic cleaning equipment is limited, cause roller brushes structure, one-level air channel 4 and cleaning object Arranging between storage member 2 grade is extremely compact, and joint space-efficient mode is by complete for one-level air channel 4 Entirely arrange along z-axis, but that can lose air quantity significantly, thus be substantially reduced suction efficiency;And in the disclosure Embodiment in, under the conditions of limited inner space, by increasing between the first side wall 43 and z-axis Angle, can do wind direction and guide obliquely, after making wind enter the inside of cleaning object storage member 2, After the wide-angle reflection of inwall top side 23, by the filter screen (not indicating in figure) at air outlet 22 to connect The direction of nearly level is discharged, and the wind path design of a this wide-angle reflection is the least to the loss of air quantity.And In the related, when using, in order to save space, the wind path derived straight up by wind completely, due to Wind experience straight up turns the result of mouth and is reflected down, thus air quantity can led after upwards impact Lose in a large number at mouth to turning of level.On the other hand, wind is derived straight up by avoiding, can keep away Exempt from the moment shut down at automatic cleaning equipment, cause and drop out still in the cleaning object in one-level air channel 4 The external world, causes the secondary pollution to ground.
Further, due to one-level air channel 4 arrival end 41 towards the round brush 11 of lower left, the port of export 42 even It is connected to clean the air intake vent 21 of object storage member 2, thus one-level air channel 4 is by right to cleaning for wind guiding As storage member 2 internal time, wind and the cleaning object swept along thereof can be made directly to blow to clean object incorporating section The inwall top side 23 of part 2;And owing to wind is when directly blowing to top side 23, clean object storage member 2 Air outlet 22 not at this top side 23 at so that at top side 23 occur big angle of incidence anti- Penetrate, after conversion wind direction, entered light breeze road 5 by air outlet 22;After wind enters cleaning object storage member 2 Sectional area becomes big, causes the decline of wind speed, cleaning object to be fallen at top side 23 due to wind speed decreased, Thus reside in cleaning object storage member 2;Simultaneously as wind speed decreased and the change of wind direction, institute Although air outlet 22 can be blowed to wind self and enter light breeze road 5, but cannot continue cleaning right As blowing at air outlet 22, thus when cleaning object storage member 2 is at dirt case assembly and air outlet 22 When being provided with filter screen 24, can avoid cleaning object and directly be blown to filter screen 24 surface, it is right to prevent from cleaning As the surface of filter screen 24 is caused obstruction, contribute to promoting air quantity utilization rate.
Additionally, when cleaning object storage member 2 and being dirt case assembly, as shown in Figure 8, this dirt case assembly The sidewall 25 being provided with air intake vent 21 is detachable, and when this sidewall 25 is removed, can be formed and be used for inclining The pour spout 26 of the cleaning object of storage in the case assembly of falling dirt.Owing to air intake vent 21 is arranged on sidewall 25, Thus the specification of sidewall 25 is naturally larger than air intake vent 21, so after being dismantled by sidewall 25, rule can be formed Lattice are more than the pour spout 26 of air intake vent 21, it is simple to the cleanings such as user's dust to collecting in dirt box structure are right As toppling over.

As an exemplary embodiment, the cleaning member 1 in the automatic cleaning equipment of the disclosure can be rolling Brush assemblies.Fig. 9 shows the perspective view of the main brush module in round brush assembly, and Figure 10 is Fig. 9 The decomposition texture schematic diagram (visual angle in Figure 10 is for observing from bottom to top along z-axis) of shown main brush module; As shown in figs. 9-10, this main brush module can include round brush 11 and round brush storehouse 12, and round brush storehouse 12 enters one Step includes floating system support 121 and round brush lid 122.
1) round brush 11
Figure 11 shows the structural representation of round brush 11.As shown in figure 11, the round brush in this round brush assembly 11 can be glue hair mixing brush, is i.e. provided with glue brush part 112 and hair in the rotating shaft 111 of round brush 11 simultaneously Brush part 113, so can take into account the multiple cleaning ambient such as floor, woollen blanket.The adhesive tape of glue brush part 112, The direction of growth of the hairbrush of hairbrush part 113 is basically identical with the radial direction of rotating shaft 111, and glue brush part 112 Adhesive tape width, hairbrush part 113 hairbrush width basically identical with the width of the arrival end 41 in one-level air channel 4; Wherein, the micro-row being bent upwards in centre shown in Figure 11 be a glue brush part 112, in undaform one Row is a hairbrush part 113, and each round brush 11 can include at least one glue brush part 112 and at least one Individual hairbrush part 113.
Glue brush part 112 is not taked with hairbrush part 113 parallel or connects subparallel set-up mode, but two There is bigger angle, to guarantee that glue brush part 112 and hairbrush part 113 can each realize self between person Application function.
(1) glue brush part 112
Owing to there is bigger gap between brush tuft 113A on hairbrush part 113 so that wind be easy to from Running off between gap, the help to forming vacuum environment formation is smaller.Therefore, by arranging glue brush part 112, effect of going for a drive can be formed, and when intensity of going for a drive reaches preset strength, it is right to assist to realize The sweeping of cleaning object so that cleaning object can be more convenient under the blowing of the sweeping of round brush 11 and wind Be transported to clean in object storage member 2.
Wherein, the glue brush part 112 setting direction in the face of cylinder of round brush 11 and the side of setting of rotating shaft 111 More hour, glue brush part 112 is completely along the setting of rotating shaft 111 the most in the limiting case for angle between to Direction carries out straight line arrangement, when the x-axis along embodiment illustrated in fig. 11 is arranged i.e. completely, and glue brush part 112 Maximum can be formed go for a drive intensity.
And on the basis of in view of intensity of going for a drive not less than above-mentioned preset strength, the disclosure is further Combine considering of other factors.Than in embodiment as shown in figure 11, glue brush part 112 is the most not Arrange fully according to straight line, and arrange along the mode close to straight line in being utilized in the face of cylinder of round brush 11 Cloth, and make the centre position rotating direction end bend to round brush 11 of glue brush part 112, so that power The wind that parts 3 produce converges in glue brush part 112 and forms the centre position of bending, thus can enter one Walk and cleaning object is collected.And on the other hand, the glue brush part 112 of complete lineal layout can only obtain The maximum of moment is gone for a drive effect, arranging of certain angle of bend can be by the round brush 11 in rolling process Effect of going for a drive keep a period of time.
It practice, as shown in Figure 10, by being pointed to one-level air channel 4 and the rolling of oblique upper, round brush storehouse 12 Brush 11 carries out contrast and understands: on width (or left and right directions), the specification in one-level air channel 4 is less than Round brush 11;Wherein, limited air quantity can be utilized to realize bigger static pressure compared with the one-level air channel 4 of small dimension Value, it is simple to being delivered to cleaning object clean object storage member 2, the round brush 11 of bigger specification then may be used To realize bigger cleaning area, so above-mentioned size heterogeneity is actually in the lifting to cleaning efficiency And the design means taked.So, by the shape of glue brush part 112 is carried out reasonable disposition so that wind Collect to the centre position of glue brush part 112, above-mentioned size heterogeneity can be matched with, it is ensured that will be all The cleaning object swept by round brush 11 all sends into one-level air channel 4, and is delivered to further clean object storage In parts 2.
It addition, in Figure 10 it can be seen that floating system support 121 have at air intake (lower end in figure) to The wind path in one-level air channel 4 guides arc structure 1211, and this arc structure 1211 and one-level air channel 4 Arc shape 40 is that curvature is consistent, thus this arc structure 1211 improves wind and enters the efficiency in air channel, Decrease wind loss.
(2) hairbrush part 113
In embodiment of the disclosure, hairbrush part 113 is in the face of cylinder of round brush 11 and between rotor shaft direction Form relatively large deviation angle;For each hairbrush part 113, by forming above-mentioned relatively large deviation angle, can Make some brush tuft 113A of this hairbrush part 113 of composition along rotor shaft direction arrange successively time, in the circumferential Realize the bigger angle of coverage to round brush 11, such as the circumferential angle of coverage of round brush 11 is reached preset angle Degree.
